Engineering is like paying a mechanic to put a turbocharger in your car, except the mechanic makes you source every bolt and nut yourself. Drive to another country to pick up the turbocharger itself, then drive it back to him with 300 different kinds of seals, gaskets, screws and other fittings. Oh no, did you forget the hand towels? His hands are dirty, go drive another 400 miles and get towels and soap so he can clean up!!!
Pretty sure I've used
exactly the same analogy myself, in the past.
Added to which (in the past, at least), it was kind of like going to TurboTechnics for a car mod', having them tell you that you've got to find the parts yourself
and then, when you do bring the stuff they need, you might've ended-up with a 10hp gain, or a 50hp gain or (if you were really lucky) a 100hp gain.
At least the new engineering procedure ensures your effort gets you the gain you expect, rather than just a random gain.
It'd be nice if we could (to continue the analogy) go and try to find a scrap car that already had the upgraded turbo, attempt to steal an upgraded turbo from a shop that sells them, get to know somebody who can get us an upgraded turbo or simply attack somebody who's already got an upgraded turbo and salvage it from the burning wreckage of their car.
In addition to the current "bring somebody the components" method that we already have.
